IPC: A61C11/08
Abstract: 106,650. Hall, R. E. May 25, 1916. Teeth, artificial.-In apparatus for articulating the teeth before they are worn, provision is made for transverse as well as up-anddown movement of the teeth. Mounted in an extension 18, Fig. 1, of the rigid base 19 is a spindle 20, to which an arm 21 is adjustably secured and carries a transverse hinge 24 with an upwardly-directed leaf 26 forming a nut for a bolt 25 secured to the upper jaw model 11 by means of a flanged plate 32 with a nut 36 adapted to be embedded in the model. Movement about the two axes is regulated by means of controlling- studs 40, 31 with their associated parts, and the adjustment of the incisors is effected with the aid of a longitudinally slidable rod 41 clamped to the upper-model plate 32 and having a spherical lower end bearing against transversely inclined camplates 43 mounted to rock about a longitudinal axis. These cam-plates are adjusted to produce the desired ground angle of the teeth and further prevent excessive displacements of the upper model. The lower-jaw model 12 is secured to the rigid base by means similar to those provided for securing the upper model to the leaf of its hinge.

Title: Improvements in or relating to extrusion machines
IPC: B29C48/03
Filed: 1942-07-31
Abstract: 559,155. Extrusion machines. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., and GRIFFITHS, F. T. July 31, 1942, No. 10785. [Class 87 (ii)] [Also in Group XXII] In a machine having a pair of axially-aligned screw impellers which are integrally united or mechanically coupled at their delivery ends, the cross-sectional area of the machine casing is substantially reduced between a heated and an adjacent cooled part thereof to ensure better heat control of the parts. Fig. 1 shows a machine having two parallel pairs of screws working in barrels 8 ; as described in Specification 559,153. A deep circumferential recess 23 is formed in each.barrel between electric heaters 16 which heat the feed end and cooling-water passages 17 which cool the material (e.g. lead) in the screw cylinder 9 to reduce it to a plastic state in which it can be gripped by the screw. Alternatively, the recess may be formed in the interior of the barrel, as shown at 24. The end part 25 may be reduced, as shown by the dotted line 25a, or most or all of the end part may be removed. To minimize the risk of thermal distortion, the casing is mounted, trunnion-fashion, in bearings 52 on pedestals 53, leaving the feed ends free to expand outwards ; alternatively the casing may carry feet which are supported on the pedestals 53. In a modification, each barrel 8 is in three parts, the two end parts being held in spaced relation to the centre part by bolts. There is an axial outward thrust on the cylinders 9 ; this may be confined to the central parts of the barrels by anchoring the cylinders in the barrels at the delivery ends, as by screwing them into the barrels, in which case feather keys which restrain the barrels from rotating are not used. In a further modification, the recesses 23 are formed between burners and air or water jets playing on the rotating barrels of a single-pair-of-screws machine having a stationary axial tubular core which carries the dies.

Title: Production of synthetic toluene from petroleum
IPC: C07C5/387
Filed: 1943-07-05
Abstract: Toluene is produced from a naphthenic petroleum distillate by fractional distillation thereof to separate a dimethyl cyclopentanemethyl cyclohexane fraction containing a major proportion of the dimethyl cyclopentanes and having an initial boiling point between 185 DEG  and 197 DEG  F. and a final boiling point between 218 DEG  and 232 DEG  F., contacting this fraction with a molybdenum oxide catalyst under "hydro-forming conditions" to convert dimethyl cyclopentane to toluene and recovering substantially pure toluene from the product.  "Hydro-forming conditions" are defined as temperatures of 800-1000 DEG , preferably 850-950 DEG  F., pressures of 1-50, preferably 4-12 atm., liquid hourly space velocity of 0.1-1.2, and a molar ratio of hydrogen to hydrocarbon of at least 1 : 1, preferably above 3 : 1.  Under these conditions, reaction is in the vapour phase.  The molybdenum oxide may be used alone, as a mixed gel or supported on active alumina, magnesia, carbon, or clay, or in other known manner.  It is preferably supported, alone or with promoters, upon adsorptive alumina in the form of a -alumina monohydrate or gamma alumina which may be stabilized with an alkali or alkaline earth metal oxide, the concentration of molybdenum oxide being about 4-30 per cent by weight.  The catalyst may form a fixed or moving bed or may be in a finely-divided dispersed state.  The product may be fractionated to remove materials boiling above toluene and the latter then recovered in known manner, for example, by adding a higher boiling paraffinic naphtha such as kerosene and extracting the mixture with liquid sulphur dioxide.  The conversion of the dimethyl cyclopentanes to toluene is illustrated by the action of a molybdenum oxide-alumina catalyst containing 14 per cent of the former on a straight-run gasoline fraction boiling at 185-197 DEG  F. which contains 67 per cent by volume of naphthenes consisting of 1,1-, 1,2-, and 1,3-dimethyl cyclopentane, at 914 DEG  F., 5 or 10 atm., contact time of 100 secs., and a molar ratio of hydrogen to hydrocarbon of 3.

Title: Improvements relating to slack adjusters for braking apparatus
IPC: F16D65/52
Filed: 1920-04-20
Abstract: 144,615. Redford, J. E. June 12, 1919, [Convention date]. Compensating for wear.-In an automatic slackadjusting device for brake mechanism, relative movement of the two elements of an extensible member of the mechanism is prevented during the application of the brakes by a pair of interengaging nuts engaging spiral grooves of opposite pitch on one of the elements, and if excess movement of the mechanism occurs a spring is compressed which is able to extend the member during the release movement. The extensible member comprises a casing 1 connected to one brake lever 2 and a rod' 3 connected at 16 to another brake lever 4. A pair of nuts 7, 8 with interengaging teeth 10 engage spiral grooves 5, 6 respectively on the rod 3. A spring 24 bearing on the nut 7 and the part 25 of the casing 1 urges the teeth 10 into engagement. A spring 11 is disposed between the reduced end of the rod 3 and a rod 12 provided with an arm 14 having a slot 15 through which the pin 16 passes. A member 18 sliding on the rod 12 engages a groove 20 in the nut 7 and serves as an abutment for a spring 21 bearing on a tilting ring 22 which abuts against a projection 23 on the casing 1. If there is excess movement of the levers 2, 4 with respect to the member 1, 3, in an application of the brakes, a pin 26 on the lever 4, acting on the arm 14, moves the rod 12 and compresses the spring 11, the pin 16 moving towards the left-hand end of the slot 15 and the engagement of the teeth 10 of the nuts 7, 8 preventing inward movement of the rod 3 with respect to the casing 1. When the brakes are released, return movement of the rod 12 is prevented by the ring 22, and the spring 11 moves the rod 3 outwardly until the clearance at the right of the pin 16 has been taken up, the teeth 10 permitting rotation of the nut 8 in the direction which allows this movement of the rod 3. The nuts 7, 8 may be separated and the locking- ring rendered inoperative by a handle 27 on the member 18 to permit manual adjustment of the extensible member in either sense.
